Osphena and Breastfeeding
Osphena (ospemifene) has not been studied in women who are nursing, so it is unknown if this drug would pass through breast milk or if it would harm a nursing infant. However, Osphena is not meant for use in women who are breastfeeding; it is only approved for women who have gone through menopause.
Osphena™ (ospemifene) is a prescription medicine approved for treating moderate-to-severe painful sexual intercourse (known medically as dyspareunia) that is a symptom of vaginal changes due to menopause. It belongs to a group of medicines known as selective estrogen receptor modulators (SERMs). Like other SERMs, Osphena binds to estrogen receptors and acts like estrogen in some areas of the body, but blocks estrogen receptors and acts like an anti-estrogen in other areas of the body.
At this time, it is not known if Osphena passes through breast milk in women. Therefore, if you are breastfeeding, talk with your healthcare provider before taking this drug.
Osphena has been shown to pass through the breast milk of rats. The drug has not been studied in breastfeeding women, however. Therefore, it is unknown whether Osphena passes through human breast milk or if it would harm a nursing child.
It is important to point out that Osphena is not approved for use in premenopausal women. This includes premenopausal women who are breastfeeding.
You should discuss breastfeeding and Osphena use with your healthcare provider. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, the two of you can make a shared decision that is right for you.
